4 Claims.

The present invention relates to a method of packing sealing disks for bottle cap shells and the like, in which, in a manner known per se, the 'disks are stacked in a tube or some other guide and then the pile or the row of disks are rolled into wrapping material upon a moving support, preferably consisting of rollers. The invention also relates to a device for carrying out the method. According to the invention provisionis' made for'ins'pecting and controlling the disks during the packing operation, such controlling being impossible after the packing, because the disks are, in a packed condition, inserted in the magazine of the capping machine. The invention is characterized thereby that the pile of disks is placed on the support and by means of'the same is put into rotation around its own axis freely and visibly, the pile of disks, by cooperation of the support with at least one roller, adapted to be pressed against the pile from above, being then rolled into the wrapping material,

A machine for carrying out the method according to the invention is shown diagrammatically in the accompanying drawings.

Figure 1 is a side view of the machine in inoperative position, some parts to the right of the line I-I of Figure 3 being omitted or only diagrammatically shown.

Figure 2 is a view from the same side, some parts being omitted and others being in Working positions so as to illustrate the mode of operation of the machine.

Figure 3 shows a plan view.

The frame I of the machine carries a Work table in and the rollers, by means of which the pile of disks is rolled into wrapping paper or the like. The supporting rollers r, s are stationarily mounted so close to each other that they are able to carry the pile of disks put down in the slot between the two rollers. The bearings of the rollers are indicated by T1. In the frame, below the rollers, there is mounted a driving shaft 01, provided with a gear-pinion k meshing with toothed wheels in of the roller shafts. The source of power used in this embodiment is an electric motor on, by means of which the shaft (1, via a worm gear in, v2 after the connecting of a clutch 702, may be driven. The clutch shown, a common friction clutch, is automatically connected by means of a spring I, but is brought out of the position of engagement by pressing down a treadle t1, which is connected with the sliding part of the clutch by means of a crank 22, an articulated rod Z1 (Fig. 1) and an angle lever 03.

The shaft it may be rotated also by hand by means of a handwheel 1'2. Above the rollers r, 8 there is a third roller t, mounted at either end in bearing members l2, which are swingable on two axle ends (12 in such a manner (Fig. 2) that the roller can be approached to and moved away from the two otherrollers'. The two bearings and the roller t are moved to their two extreme positions by means of two bars m, which by means of two levers h are united with an operating' member; for example, the treadle t1, so that the roller 15 is raised, when the treadle is depressed, the clutch being at the same time disengaged by means of the members 1), Z1 and in. When the treadle is released the roller 2'? is lowered against the rollers r, s and the clutch is engaged by the action'of a spring f; which with its one end is fixed in the frame and with its other in the treadle. The spring may be provided also at some other place and may act by pressure. At the ends of the rollers there are shoulders SC, in, the left of which in Figure 3 is hinged and springing. If desired, the right shoulder may be arranged in the same manner.

The packing operation is effected in the machine in the following manner: The abovementioned tube (not shown) with disks in it is placed in the slot between the rollers r, s, one end of the pile is pressed against the shoulder a: (Fig. 3) and from the pile of disks thus placed the tube is drawn over a mandrel (not shown) in a manner known per se. The disks (11 will then lie in a pile in the slot between the two rollers. The disks are retained in their positions between the shoulders w, an by the spring pressure of one of the same, in which case they stand perpendicularly to the rollers r, s so that they may be easily inspected, during the rotation, which rotation is efiected by the rollers r, s and the handwheel r2. Disks, which may have become damaged, may be substituted. The treadle is then released and the two rollers T, s are set into rotation in the direction of the arrows at the same time as the upper roller t is pressed against the disks. The wrapping paper is introduced between the roller 1" and the pile of disks and by the rotation of the two rollers 'r, s, in which rotation also the disks and the roller t take part, the wrapping paper is put around the disks. If desired, guides may be provided between the rollers, which contribute to the guiding of the wrapping paper during this motion. Figure 3 shows a number of guides u placed on a support a. After the wrapping paper having been out ed to a suitable length a corresponding number of gummed paper strips are put between one of the rotating rollers and the wrapping paper surrounding the pile of disks. The gummed strips follow the wrapping paper and close the packing roll. However, the closing may be effected by pasting the roll together along its longitudinal side. The roller t is then returned to the position shown in Figure 1, by the treadle being operated; at the same time the clutch is disconnected so that the rollers stop. Finally, the ends of the packing roll are folded in a suitable manner so as to prevent the disks from falling out. With that the packing operation is finished.

If the treadle is to be kept depressed for some considerable time it is possible to lock it in such position by means of a locking member, for example, a bar s1, which is swingably mounted in the frame, at .92, so that the machine operator is able to swing the same to above the treadle, as shown in Figure 1. Of course, the locking may be effected by an ordinary catch.

The machine is of a particularly simple construction and is easy to operate. Of course, the invention is not, however, restricted to the embodiment shown. More rollers than three may be used the distance between them being then reduced. Also, the driving device may be of some other construction, for example, the machine may be disconnectibly coupled to a driving shaft common to several machines.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An apparatus for packing sealing disks used in bottle cap shells, comprising slightly spaced supporting rollers upon which a row of disks are placed, mechanical means to drive said rollers, an overhead roller movable into rolling contact with the disks to guide wrapping material over and against the disks beyond the rollers and to be moved away from the disks before being wrapped to permit inspection thereof and again after wrapping to remove the package and manually operative means to move the overhead roller.

2. An apparatus for packing sealing disks used in bottle cap shells, comprising slightly spaced rotary supporting rollers upon which a pile of disks are placed, control means for starting and stopping the rotary movement of the supporting rollers, an overhead roller movable into rolling and pressure contact with thedisks to guide wrapping material over and against the disks beyond the rollers, and connecting means between the control means and overhead roller to move the latter out of engagement with the disks when the supporting rollers are at rest to permit inspection of the disks before wrapping and removal of the same after wrapping and to move the overhead roller into operative engagement with the disks when the supporting rollers are in rotation.

3. An apparatus for packing sealing disks, as claimed in claim 2, including further means to free the supporting rollers from rotary driving movement, whereby the rollers are free to be rotated manually while the disks are under inspection.

4. An apparatus for packing sealing disks, as

claimed in claim 1, including end supports for the ends of the row of disks on the supporting rollers, one at least of said end supports being yieldably mounted to exert pressure on the row and means for moving the yieldable end support out of operative position with respect to the disks.
